JULIUS A. BERNINGHAUS, OF ST. LOUIS, MISSOURI.

ELECTRIC HEATER.

Application led January 21, 1922. Serial No. 530,764.'

T o all whom it may concern: n

Be it known thatv I, JULIUs A. BERNING- HAUS, a citizen of the UnitedStates, residing at the City of St. Louis, in the State of Missouri,have invented certain new and useful Improvements in Electric Heaters,

of which the following is a specification.

. means of turning on or oil' an electric motor in conjunctiontherewith.

In the accompanying drawings forming part of this specification, inwhich like numbers of reference denote like parts wherever they occur,

Figure 1 is a side elevation; and

Figure 2 is a side elevation taken at a right angle to Figure 1.

The base 1 contains grooves or depressions v 2 adapted to receive lugs 3by which motor 4 is attached to base 1 by means of screws 5.

Motor 4 is mounted well within the circumference of base 1 and helps toweight the same and to keep the entire device compact. It is mounted asnear as possible to central standard 6 and well within the circumference7 of base 1.

A fan 8 having blades 9 is mounted on base 1 and the shaft'10 of motor 4adapted to rotate the blades 9. Holes 11 in the housing of fan 8 permitthe suction of air into pipe 12, by which the air is conducted into theencircling chamber 13 formed on or in connection with the radiator 14,there being a'plurality of holes 15 acting as passages from the interiorof chamber 13 to the space within the basin of radiator 14.

When the air forced through pipev 12 into chamber 13 strikes the wall ofbasin or radiator 14, the said material acts like a baffle to cause theair to travel in two directions, as indicated by the arrows in vFigure2.` Furthering this object, the holes 15 nearest the mouth or exit 16from pipe 12 are smaller in diameter than the holes'l found further awayfrom the said mouth 16,

and it is the intention that the same shalll preferably graduate insize. Thus it will result that the air emit-tedthrough pipe A12 will ndits way all the way around chamber 113 and thus all become hea-ted bymeans of the coil 17 of resistance wire, whereas if the holes near mouth16 were as large as those vfurther away therefrom, such air would nothave time to become heated and the eiiicienc of the heater would berelatively much d1- minished thereby.

By the radiator 14 being directed upward,y as shown 1n Figure 1, atendency is at once created to force the warm air upwardly, while thesuction through holes 11 tends to draw the cold air'from the bottom ofthe room or the floor, this combined action tending immediately .to setup a current of warm air rising toward the ceilinga and of cold airdescending toward the floor, whereby the` temperature of all parts ofthe room is most quickly equalized.

The radiator 14 ispivoted at 18 to central-standard 16, and if pipe 12be made telescoping or ofiiexible material or of extensible members, thedirection of tilt of radiator 14 can be changed at will, so as to directthe hot air in various directions.

The wire 19 conducts the electric current to the coil 17 and causes thesame to evolve` draft or suction of air to be4 heated. The

motor 4 is fed by branch wires 21,

Having thus described this invention, I hereby reservethevbenefit of allchanges in form, arrangement, order, or use of parts, as it is evidentthat man minor changes may be made therein wit out departing from thespirit of this invention or the scope of the following claims.'

I claim:

1. In an electric heater thev combination of a radiator having holes, anair chamber 1n connection therewith, an air pipe leading to the saidchamber, and a fan.

2. In an electric heater the combination of a radiator having holes, anair chamber 1n connection therewith, an air ipeY leading to the saidchamber, a fan,.an a motor:

3. In an electricyheater the combination of a radiator having holes, anair chamber in connection therewith, an air pipe leading to the-'saidchamber, a fan, a motor, and a switch.

4.' In an electric heater the combination of a radiator, a coil, an airchamber, a pipe leading thereto, air passages between the said chamberand the said radiator, electric connections for the said coil, a fan inconnec tion with the said pipe, a motor whereby the said fan isoperated, and branch electric connections for the 4said motor.

5. In an electric heater the combination Oi' a radiator, a coil, an airchamber, a pipe leading thereto, air passages between the said chamberand the said radiator, electric connections for the said coil, a fan inconnection with the said pipe, a motor whereby the said fan is operated,electric connections for the said motor, and a switch, whereby the saidmotor and fan majyv berende'rled inoperative without affecting the saidco1 6. An electric heater comprising a radiator having holes, an airchamber communieatingl with the 4said radiator through the said holes,an air pipe leading to the said air chamber, a fan communicating withthe said pipe, and means for operating the said fan, the said holesbein@r of less diameter near the said pipe than further away.

In testimony whereof I hereunto affix my signature.

JULIUS A. BERNINGHAUS.
